How to convert high voltage 500 volts DC at very low amps to lower voltage 12 volt DC or AC at high amps? Must I use an electrostatic motor or can I use an op amp?

The reason I am posing this is a desire to send up a wire to convert atmospheric electricity to something I can use.

  • \$\begingroup\$ You may be able to design a special-purpose DC-DC converter, but... What is the atmospheric electricity you reference? \$\endgroup\$ – Hearth Nov 7 '18 at 21:32
  • \$\begingroup\$ The 500 volts is a rough estimate of the voltage from the ground to the roof of my house. Unfortunately, the current would be in picoamps. I once saw an article about a boy who developed enough amps to charge a cell phone from a vertical wire. \$\endgroup\$ – Bruce Patin Nov 9 '18 at 17:14

You might be able to adapt something from the "solar engine" guys. They have a lot of circuit variants that take small amounts of charge and store it in a capacitor until enough energy is available, then discharge it all at once to do something useful. Due to your input voltage you'll have to pick appropriately rated transistors.
